New World Bank funding will strengthen climate change adaptation and resilience in flood-prone Dar es Salaam, United Republic of Tanzania


WASHINGTON, Oct. 4, 2022—New funding approved by the World Bank Executive Board will help reduce flood vulnerability for over 300,000 people, including many in low-income communities, while providing access to better infrastructure and services. It will also help transform a flood-prone area in the city center into a vibrant green space, commercial and residential area that will benefit all Dar es Salaam residents.

In addition, users of the city’s Bus Rapid Transit system and other commuters will benefit from less disruption from flooding during the rainy season through the implementation of the new Msimbazi Basin Development Project, funded with $200 million by the International Development Association (IDA ) is financed )*.

Harnessing urbanization to boost economic growth and job creation is a priority in our Country Partnership Framework for Tanzaniasaid** Preeti Arora, Acting Country Director for Tanzania** at the World Bank. “Despite its critical role as a growth engine for the nation, Dar es Salaam’s business environment is negatively impacted by the unplanned nature of its growth, limited city services and the vulnerability of settlements and critical infrastructure to climate-related hazards. This new support will help transform the city into a more efficient metropolitan area.”

With an estimated six million inhabitants, Dar es Salaam accounts for 40% of Tanzania’s total urban population and 17% of the national GDP. With an annual growth rate of 5.6%, it is expected to become a megacity with more than 10 million inhabitants by 2030. Formal planning has not kept pace with the city’s population growth. An estimated 70% of development in the city is informal and unaccompanied by service upgrades, leaving the booming urban population with infrastructure systems befitting a much smaller city.

Given Dar es Salaam’s flat topography and limited drainage network, flooding occurs almost every wet season, and the area near the lower Msimbazi River is hardest hit. This has become increasingly severe over the past decade due to rapid and unplanned growth, resulting in higher flood intensity and more people moving to flood-prone areas.” said John Morton, senior urban specialist at the World Bank. “The project is designed to withstand this rapid urbanization and the expected impacts of climate change through a flood prevention approach that reduces impacts on mobility, property, health, livelihoods and economic development.”

The new project, whose development objective is flood resilience and integrated urban development in the economically important and flood-prone area of ​​the Msimbazi River Basin, will consist of five components: (1) the Msimbazi River Basin Development Infrastructure; (2) preventive resettlement; (3) strengthening institutions for resilient urban development; (4) project management; and (5) conditional emergency response. It is co-funded by a $30 million loan from the Spanish Agency for International Development Cooperation and a €30 million grant from the Dutch Ministry of Foreign Affairs.

The project was designed with grants from the UK Departments of Foreign, Commonwealth and Development, which supported baseline assessments and facilitated the identification of project intervention stakeholders. The Japanese government’s Nordic Development Fund and Quality Infrastructure Investment Partnership and the Tokyo Development Learning Center contributed knowledge and technical advice on green infrastructure.

The project also builds on the World Bank’s nearly two decades of involvement in urban development in Dar es Salaam, including the Dar es Salaam metropolitan development projectwhich will be closed in December 2022.

Public spaces and green space are scarce, only 2% of Dar es Salaam is classified as public green space and only 0.1% as park. While much of the project area in the lower Msimbazi Valley is open space, the quality of the green space, wetlands, forests and riverbanks has been degraded due to urban pressure, deforestation and landfill. The project will also benefit the population of Dar es Salaam from the city’s first large urban parksaid** Allen Natai, Senior Transport Specialist at the World Bank.*

* The World Bank’s International Development Association (IDA), founded in 1960, helps the world’s poorest countries by providing grants and low-to-no interest loans for projects and programs that boost economic growth, reduce poverty and improve the lives of poor people. IDA is one of the largest sources of aid to the 74 poorest countries in the world, 39 of which are in Africa. IDA resources create positive change for the 1.3 billion people who live in IDA countries. Since 1960, IDA has provided $458 billion to 114 countries. Over the past three years (FY19-FY21), annual commitments averaged about US$29 billion, of which about 70 percent went to Africa. Learn more online: #IDA works
